## NAME
       ximtoppm - convert an Xim file into a portable pixmap

## SYNOPSIS
       **ximtoppm** [**--alphaout=**{_alpha-filename_,**-**}] [_ximfile_]

## DESCRIPTION
       Reads  an  Xim  file as input.  Produces a portable pixmap as output.  The Xim toolkit is in‐
       cluded in the contrib tree of the X.V11R4 release.

## OPTIONS
       **--alphaout=**_alpha-filename_
              **ximtoppm** creates a PGM (portable graymap) file containing the alpha channel values  in
              the input image.  If the input image doesn't contain an alpha channel, the _alpha-file__‐
              _name_ file contains all zero (transparent) alpha values.  If you  don't  specify  **--al**‐‐
              **phaout**,  **ximtoppm** does not generate an alpha file, and if the input image has an alpha
              channel, **ximtoppm** simply discards it.

              If you specify **-** as the filename, **ximtoppm** writes the alpha output to Standard  Output
              and discards the image.

              Actually,  an  Xim  image can contain an arbitrary fourth channel -- it need not be an
              Alpha channel.  **ximtoppm** extracts any fourth channel it finds as described  above;  it
              doesn't matter if it is an alpha channel or not.

              See [**pnmcomp**(1)](https://www.chedong.com/phpMan.php/man/pnmcomp/1/markdown) for one way to use the alpha output file.


       All options can be abbreviated to their shortest unique prefix.
